Adapt commit to use file matching code. The code is slightly complicated by the need to commit all outstanding changes in the repository if no file names are given (other commands operate on the current directory and its subdirectories in this case). localrepository.changes has acquired an optional match parameter, to let it filter out include/exclude options.
